The San Francisco Police officer responsible for shooting a fleeing suspect in the back on a crowded North Beach sidewalk earlier this month was also responsible for the deadly shooting of a 15-year-old back in 2012 while he was an officer with the South San Francisco Police Department.

Gaines was shot and killed at an Arco station in South San Francisco back on June 5, 2012.

On that night, Gaines and a friend were walking through the Arco station at the corner of Westborough and Gellert Boulevard in South San Francisco. Police Officer Joshua Cabillo approached the two because they were acting suspiciously. Surveillance video shows Gaines running away. When Cabillo caught up with him, there was a confrontation. The San Mateo County district attorney said Gaines had a gun and reached for it and that's when Cabillo opened fire.

What Cabillo didn't know at the time was that the gun was inoperable, missing a firing pin.

After a 3-month investigation District Attorney Steve Wagstaffe declined to file charges against Cabillo.

"Clearly the most significant factor was the existence of this .45 caliber firearm that the young man had in his possession and was reaching for at the time the officer made the decision to fire and kill him," Wagstaffe said at the time.

The family of Derrick Gaines filed a civil rights lawsuit against the South San Francisco Police Department and Officer Cabillo after the investigation was complete.

As for the San Francisco shooting, investigators say that Officer Cabillo remains on administrative leave and that the shooting remains under investigation.
